On the stability of Murray's testosterone model [PDF]
arXiv, 2004 We prove the global asymptotic stability of a well-known delayed negative-feedback model of testosterone dynamics, which has been proposed as a model of oscillatory behavior. We establish stability (and hence the impossibility of oscillations) even in the presence of delays of arbitrary length.

Journal of Ovarian Research, 2023 Background Many epidemiological studies have shown that anovulatory polycystic ovary syndrome (PCOS) is accompanied by hyperandrogenism. However, the exact mechanism of hyperandrogen-induced anovulation remains to be elucidated.

Action spectroscopy of gas-phase carboxylate anions by multiple photon IR electron detachment/attachment [PDF]
, 2008 We report on a form of gas-phase anion action spectroscopy based on infrared multiple photon electron detachment and subsequent capture of the free electrons by a neutral electron scavenger in a Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometer.

Treatment of constitutional delayed puberty with a combination of testosterone esters
The Turkish Journal of Pediatrics, 1993 Thirteen boys with constitutional delayed puberty (CDP) were treated with a combination of short and long-acting testosterone esters (testosterone propionate, testosterone phenylpropionate, testosterone isocaproate).

The ability of fruit and vegetable enzyme system to hydrolyse ester bonds
Acta Societatis Botanicorum Poloniae, 2014 The pulp of potato tubers (Solanum tuberosum), topinambur (Helianthus tuberosus) and apples (Malus silvestris) can hydrolyse totally, or almost totally, ester bonds in phenyl, α- and β-naphthyl, benzyl and cinnamyl acetates.

A three-phase chemical model of hot cores: the formation of glycine [PDF]
, 2013 A new chemical model is presented that simulates fully-coupled gas-phase, grain-surface and bulk-ice chemistry in hot cores. Glycine (NH2CH2COOH), the simplest amino acid, and related molecules such as glycinal, propionic acid and propanal, are included in the chemical network.

Morphological changes induced by testosterone in the mammary glands of female Wistar rats
Brazilian Journal of Medical and Biological Research, 2005 Increased levels of androgens in postmenopausal women are considered to be a risk factor for breast cancer. Testosterone, alone or in combination with estrogen, induces epithelial dysplasia and mammary tumors in Noble rats.

Local and global analysis of endocrine regulation as a non-cyclic feedback system [PDF]
, 2016 To understand the sophisticated control mechanisms of the human's endocrine system is a challenging task that is a crucial step towards precise medical treatment of many disfunctions and diseases. Although mathematical models describing the endocrine system as a whole are still elusive, recently some substantial progress has been made in analyzing ...
